Application August 3, 1931. Serial No. 554,869

3 Claims.

This invention relates to food choppers and is directed to certain improvements over the invention forming the subject matter of my pending application, Ser. No. 504,956, filed December 26, 1930, for Food choppers.

The primary objects of the present invention are to provide in such a chopper means for facilitating the application and removal, or interchange, of the presser block; to provide means preventing the incorrect or reverse mounting of the presser block; to provide automatic means for raising the presser block; to provide simple means for guiding the vertical stroke of the carriage; and to provide a light sheet metal operating handle composed of duplicate members Yadapted to be formed on a single stamping die, thus promoting the economy of production.

In the accompanying drawings:

Figure 1 represents a perspective view of a food chopper embodying my invention;

Figure 2, a cross section on the line 2--2 of Figure 4, looking in the direction of the arrows;

Figure 3, a vertical section on the line 3-3 of Figure 2, looking in the direction of the arrows;

Figure 4, a vertical section on the line 4-4 of Figure 2, looking in the direction of the arrows;

Figure 5, a sectional view on the line 5--5 of Figure 4, looking in the direction of the arrows;

Referring now in detail to the drawings, the lchopper comprisesa vertical` stand A having a flat supporting base B secured to the legs of the stand by any suitable means, such as short bolts with cooperating nuts as indicated at C.

35 The upper portion of said frame will be of elongated U-shape in cross sectionand each side of the frame is provided with a long guide slot 12, and associated with the upper part of the frame A to slide vertically thereof and guided 40 therein is a carriage consisting of two sheet metal plates 1, having their lower ends bent to extend at right angles in a horizontal direction for forming plates 2 and 2a, whichY are connected together by'means of rivets 4 passing vertically through said plates 2 and 2a and a lower plate 3, which serves the dual function of connecting said plates 2 and 2a and also serving as a support and attaching means for the presser foot 8.

A vertical series of regularly spaced preferably equal length and duplicate shape slots` 7 are formed in the back of the stand A and preferably equi-distant from the sides thereof to form a rack to receive and cooperate with the teeth of the gear lever 5 pivotally mounted between 5.5 the metal plate 1 of the sliding carriage by means (Cl. 14S-169) of a pivot pin 6 to provide an easy and simple means for forcing the presser foot 8 down toward and into the cutter 10 which is slidably mounted by means of an upper rim outwardly projecting bead 1l slidably received in the corresponding 50 horizontal groove 9 of the frame A, said cutter carrying a plurality of cutting knives E preferably arranged in two series at right angles to each other and adapted to be received in the correspondingly disposed vertical slots F in the presser 8 when the latter is moved downward. The cutter element 10 will preferably be clamped in its correct position by means of a clamp plate 16 having its upper end hooked through and adapted to slide in and guided by a perforation 7 0 1'7 in the frame A and adapted to be drawn up tightly by means of a nut 19 turning on a bolt 18 extending through said plate 16 and through a slot 20 in the rear of the frame A.

The parts as thus far described and their cooperative relations are common to said pending application, Ser. No. 504,956, and the present application and, being very fully described in detail in the former, it is not thought that further description herein is necessary or desirable.

Preferably the plates 1 of the carriage will have portions extending closely adjacent to, or in rubbing contact with, the sides of the upper Vportion of the frame A and across the respective slots 12 therein. Guiding plates 13 making a snug sliding fit in the slots 12 respectively and extending in a vertical direction for nearly the full length of the corresponding portions of the respective plates 1 are respectively held thereto 9,0 by means of outer plates 14 and pairs of screws 15 passing through said plates 14, said guide plates 13 and said portions of the respective plates 1. Said outer plates 14 will preferably have enlarged upper and lower end portions extending beyond each side of the respective slots 12 so vas to bear on the respective faces of the frame A adjacent the respective slots. The rear face portion of the presser block or foot 8 is recessed as at 8', preferably in a curved or arcuate form in a horizontal plane so as to permit said presser foot or block 8 to move downward past the rounded head of the bolt 18 and past the clamping plate 16. Said presser foot 8 is so formed as to be slidably 195 applied to, and removed from, the movable carriage in a horizontal direction from front to rear of said carriage, preferably by means of grooves receiving the respective side edge portions of the tie-plate 3 and will preferably be so related to the 110 tie-plate 3 and other portions of the carriage that it can only be slidably applied to the carriage when said recess 8 is presented rearward toward the head of the bolt i8. To this end the side portion 3a of plate 3 extending laterally beyond plate 2a will extend considerably further in that lateral direction beyond the adjacent side edge of plate 2a, than the corresponding outer side edge portionb of said plate -3 with relation to the corresponding laterally outer edge of the plate 2 with relation to the corresponding side edge portion of the plate 3, and the presser foot 8 is provided with correspondingly formed horizontal grooves 8a and 8b extending in a direction from front to rear of the block, the groove 8a being considerably Vdeeper Ythantlie groove 8b and respectively slidably receiving the portions 3a and 3b of said plate 3. 'Said block 8 is formed with a face 8c extending vertically from the inner end of the slot 8a and normally making a slidingit against the outer edge face of-plate 2a and with a similar vertical face 8d similarly-disposed with relation to the slotb and similarly makinga sliding contact with the laterally outer edge face ofthe plate 2 during the application ofthe block 8 to the carriage.

`From the foregoing it follows that if any attempt be made `to force theblock 8 on to the plate 3 when the recess or notch 8' is presented away from .the bolt v18, the upper portions of vthe block 8 respectively adjacent the faces 8c andd will strike against .thefforward ends of the `laterally portions of the vplates 2 and 2a respectively and so positively prevent kthe application of the Ypresseiwoot 8 to 4the carriage in such reversed inoperative position.

Inorder to lock or latch the block 8in proper mounted position .against displacement in a front to rear direction, I form the .upper'portion of said block '8 with a socketvor recess 22 adapted -to receive a locking .pin 23 mounted on'aleaf spring24 by any suitable means, such Aas a rivet 25, and normally Uprojecting through registering perforations in the plate 'E2 .and-plate 3 into said socket 22. Said leaf spring '241 may be mounted on the plate 2a by any suitablemeans, such as Va rivet 26 and `may be limited in kits upward Ymovement `away from 'the plate 2 by Y any suitable means, such ras a stop Yringer or lug 27 Vheld in place by one of the rivets 4. Preferably said block 8 will vbe 'formed with a rearwardly and downwardly inclined surface 21 adapted to register in a line from front to rear with the downwardly projecting end of Ythe pin 22 so as to engage Vand raise the same as the block 8 is shoved into position.

A helical tension spring 28 ,having ,its vupper endvanchored or hooked 'about a pin 30 rigidly `lnountedin the upper rearportion of the frame A'and having its lower end hooked into a little luglor cleat 29 secured to the .rear end of the plates 2 and 3 by means'of-oneiof the fastening rivetsfl serves to automatically retract thecarvriage to its raised position when the handle D is released, vand a cushioning element v3l sescured to the extreme upper portion of the frame A in line Withthe rack 7 and path'of movement "ofthe shank 5a of the'gear 5 serves'asa bumper for the `handle of said shank 5 a'of said gear 5, and said cushion 3l may be of any suitable vmaterial, such `as rubber Aor felt.

`claim is:

-tozthe outer side faces of said sides respectively and extending for their full lengths in said guide slotsrespectively, outer plates disposed on the outenfacesof `the sides of the frame in registry with said guideplates and having portions extending over and in sliding engagement with, the Youter faces of said sides of the frame adjacent fsaid guide slots respectively, and pairs of securement means extending through the respective outer plates and side portions ofsaid carriageand the respective intervening guide 2. A food comminuter comprising a frame having a guideway of channel form with parallel vertical sides formed with registering vertical guide slots, a carriage extendingbetween the sides'of said guideway andhaving side portions of substantial vertical length disposed closely adjacent, and substantially parallel, to said sides of .said guideway, in combination with vertical guide plates of substantially the same --vertical length as the respective sidesrof said carriage disposed closely adjacent, and parallel, to the outer side faces of said sides respectively and extending for their full lengths in-said guide slots respectively, outer plates disposedon the outer faces or the sides of the frame in registry -with said guide-plates and having portions extending over and in sliding engagement with,

Acarriage and .the respective intervening guide' f plates, and automatic means tending to vraise said carriageto its highest position.

3. In a foodrcomminuter comprising a frame, a carriage mounted for reciprocation in said frame, and a comminuting element adapted to 'be removably mounted in line with the path of travel of said carriage, in combination with a pair of outwardly presented vertically Aextending kfaces of portions of lsaid carriage, portions of a plate of said carriage respectively extending laterally outward beyond said vertical faces respectively, one of said portions extending'laterally to a greater distance with respect to the corresponding vertically extending 'face than the lother of said portions, and a presser `block formed with two opposed slots corresponding in position and in length in a lateral direction to said laterally extending portions of said plate of the carriage to slidably receive said portions in a direction from rear to front of said block,

and said block being formed with faces extending vertically from the inner ends 'of said slots substantially slidably engaging the respective opposedlaterally outwardly presented vertically extending faces of said portions of said carriage.
